A college dropout and Muslim convert who threatened the creators of the "South Park" cartoon series and then tried to join an Al Qaeda-linked terrorist group in Somalia has been sentenced to 25 years in prison.
Zachary A. Chesser of Bristow, Va., pleaded guilty last year to supporting the al-Shabab terrorist group in Somalia and posting online threats against the "South Park" creators for an episode he perceived as insulting to the Prophet Muhammad. He was sentenced Thursday in U.S. District Court in Alexandria.
